D-Link DCH-M225 Wi-Fi audio extender
AirPlay; DLNA; Wi-Fi extender
No 5GHz; no digital output
Like Kaiser Baas’ SoundShift, this D-Link audio extender supports 802.11n Wi-Fi networks at 2.4GHz, but not 5GHz. This limitation won’t bother some people, but if your wireless network tends to choke when someone turns on the microwave oven then you’re likely to run into trouble streaming music on the 2.4GHz band and you should consider upgrading to a dual-band 2.4/5GHz wireless network.
Wireless setup is easy, as the D-Link supports WPS, which lets you connect to a Wi-Fi network with the press of a button if your wireless router supports it (or else you can configure it manually). As a bonus, the D-Link can also act as a 2.4GHz Wi-Fi range extender, helping boost your wireless network to reduce coverage black spots around your home (it creates a second network with ‘-EXT’ added to the name).
If you don’t have a home Wi-Fi network, the D-Link can generate its own network, but there’s no Ethernet port so you can’t connect it to your broadband modem and offer wireless internet access.
The D-Link is designed to hang from a power socket, but it’s much less bulky than the Netgear and Apple’s early AirPort Expresses. There’s a 3.5mm AUX jack on the bottom for connecting to powered speakers, but no digital audio output.
Supporting AirPlay and DLNA streaming, D-Link’s Wi-Fi music adapter is also a Wi-Fi extender. You can play different songs to different D-Link adapters using different apps or devices, but it’s not a multi-room audio system and you can’t stream the same song to multiple adapters in sync.
